Default value is not a member of type "nntype.performance_fcn"

Salve, sto riscontrando il problema nel titolo quando provo a creare una rete neurale (Neural net pattern recognition). Cosa posso fare? ho appena installato l'ultimo aggiornamento della versione 2023b ma l'errore continua.

Grazie anticipatamente

Ciao Riccardo,

Non parlo italiano e affronterò la questione in inglese.

The error you’ve mentioned usually occurs when there are conflicting functions, often due to third-party packages that might have been installed. To identify the conflicting functions, run the following command in the command window:

which <function_name>

Also, you can use the ‘-all’ flag to confirm that the toolbox is installed correctly:

which -all <function_name>

If you discover conflicting third-party functions, consider packaging them into a class. You may refer to the below example for creating a wrapper class for a function named “performance_fcn”:

classdef WrapperClass 
    methods (Static) 
        function out = performance_fcn(args) 
            % The existing code 
        end
    end
end

Hope this helps!
